ROTARY ENGINE.

SPECIFICATION forming part of Letters Patent No. 394,922, dated December 18, 1888.

Application filed February 27, 1888. Serial No. 265,846. (No model.) Patented in England November 29, 1887, No. 16,420; in France February 21, 1888, No. 188,892; in Belgium February 21, 1888, No. 80,718; in Germany February 29, 1888, No. 44,899; in Italy April 28, 1888, XLV, 442, and in Austria-Hungary June 10, 1888,110. 8,939 and No. 26,151.

To all whom it may concern:

Be it known that I, RICHARD HAMMERSLEY HEENAN, a citizen of England, residing at Newton Heath Iron Forks, Manchester, in the county of Lancaster, England, have invented a certain new and useful Rotary Engine or Pump, (for which I have obtained patents in France, dated February 2]., 1888, No. 188,892; Belgium, dated February 21, 1888, No. 80,716; Italy, dated April 28, 1888, Vol. XLV, No. 442; Germany, dated February29, 1888, No. 44,899, and Austria-Hungary, dated June 10, 1888, No. 8,989/26,151, and patent in Great Britain, dated November 29, 1887, No. 16,420,) of which the following is a specification.

My invention relates to the class of spherical rotary engines and pumps forwhich British Letters Patent were granted to B. Tower,

dated October 2, 1879, No. 3,953, and United States Letters Patent were granted to G. Murray, J r., No. 221,509. For certain improve ments in such engines United States Letters Patent No. 205,380 were granted to R. ll. Froude, dated March 18, 1881 and,,further, United States Letters Patent No. 812,116 were granted to me, R. H. .llecnan, and to R. H. Fronde, dated February 10,1885.

My present invention relates to certain structural details in the manufacture of such engines,whereby I enhance their efficiency and durability, as I will describe, referring to the accompanying drawings.

Figure 1 is a front view, and Fig. 2 is a diametrical section, of the piston-disk. Fig. 3 is afront view, Fig. r a side view, and Fig. 5 a plan, of the one blade with the engim-shaft in one piece with it, the same figures representing the other blade with the short shaft in one piece with it indicated by-dotted lines. Figs. 6 and 7 are front and side views, and Fig. 8 is a transverse section in the middle of thepin for jointing one of the blades to the piston-disk. Figs. 9 and 10 are side views of the two-part pins by which the other blade is jointed to the piston-disk. Fig. 11 is a plan, and. Fig. 12 a face view, of the packing-piece inserted over each of the joint-pins.

The piston-disk A is bored through diametrically by two holes of equal size to receive the joint-pins, and at the mouth of each hole are out two slots, (1, to receive the two tongues of the packing-piece 6, Figs. 11 and 12, which is inserted to cover the end of the joint-pin.

There is also inserted in a slot in each of the four recesses of the piston a packing-piece, c. A groove, (1, turned in the edge of the pistondisk all round it, receives a spring packingring or two of these side by side. Each blade B is cast in one piece with a length of shaft,

with holes so much larger than the j oint-pins that they receive flanged bushes e, which are inserted in halves. In case of wear these bushes can be readily removed and fresh 7o bushes can be substituted. There is also in a slot in the middle recess of the blade apacking-pie ce, f, and in a' slot of each. circular edge a packingpiece, g. The slots in the piston A for the packing-pieces 0 and those in the blades 7 5 B for the packings fare most conveniently made by a revolving cutter, such as is employed for cutting keyways, and the ends of these slots being round, the packings c and f are made with rounded ends to fit the slots.

Under each of these pzwking-pieces, as well as under the packing-s h and g, may be placed thin blade-springs to press them against the surfaces which they bear upon. The joint-pin U, Figs. (3, 7, and 8, for jointing one of the blades l3 to the piston A,has through its middle a transverse hole and recess to receive the one part, I),Fig. 9, of the other joint-pin, E, Fig. 10, which has its screwed end passed through the hole in (I and screwed into the other part, 0

E, Fig. 10. The pins C, D, and E have notches 7L out where their surfaces protrude beyond the metal of the piston-disk A, so as not to interfere with the full. stroke of the blades B.

For the purpose of lubricating the working 5 parts, I drill in each blade two oblique oilholes, 0, meeting a cross-hole, p, in the shaft 8 or s, so that lubricant by centrifugal force is The blade is 65 bored diametrically through its two bosses ing through the bore, of the blade B, having bored bosses fitted with bushes 6, through which the joint-pin passes, and provided with the oblique oilrehainnels 0, leading, respect ivoly, to the interior of the bored bosses to supply the bushes and joint-pin with lubricant, substantially as described.

In testimony whereof I h ave signed my name to H1 is specification, in the1n'esenee of two subserihing wii'nesses, this 13th day of ,helnum'y, A. I"). 1885.
